2, 1, 4, 3, 5: Incorrect order; places tissue before cellular level, which is biologically inaccurate.

2, 1, 4, 5, 3: Tissue comes before cell, which is anatomically incorrect.

4, 1, 2, 5, 3: Begins at cellular, skipping the chemical level, and misorders early levels.

4, 1, 2, 3, 5: Starts too late and ends with the organ instead of the organ system.

Organization: Refers to the structured arrangement of parts from chemical to system level, not interaction with the environment.

Growth and Development: Refers to increase in size and complexity over time, not directly about environmental interaction.

Metabolism: Involves internal chemical reactions but not necessarily interaction with external stimuli.

Waste Disposal: A bodily process to remove waste, not primarily about environmental response.

Cardiovascular: Transports blood, but does not directly sense/respond to environmental changes.

Lymphatic: Supports immune function and fluid balance, but not primarily responsible for homeostasis.

Respiratory: Involved in gas exchange, but homeostasis is a secondary role.

Urinary: Eliminates waste and regulates volume, but is a response mechanism rather than a regulatory system.

After drinking large amounts of water, urine output decreases to raise blood volume:Urine output would actually increase to excrete the excess water and maintain volume.

Decreases in blood pressure cause a corresponding decrease in heart rate:A decrease in blood pressure should cause the heart rate to increase (compensatory response).

As blood pressure falls, blood flow to the heart decreases:The body usually increases heart rate and vasoconstriction to maintain cardiac output.

Axillary: Refers to the armpit area, not the abdomen.

Sternal: Refers to the breastbone or chest region, not the abdomen.

Brachial: Refers to the upper arm, not related to the abdomen.

Anterior: This means “front” of the body in general, but is too broad and non-specific. The abdomen is located on the anterior side, but “ventral” is the more precise term in this context.

Distal: Means farther from the point of attachment; applies to limbs, not the torso/abdomen.

Brachial: Refers to the upper arm area – unrelated to the abdomen.

Proximal: Means closer to the point of attachment; again, more relevant to limbs.

Frontal: A frontal (coronal) plane divides the body into anterior (front) and posterior (back) parts.

Parasagittal: A parasagittal plane divides the body into unequal right and left portions-not straight down the midline.

Transverse: A transverse plane divides the body into upper (superior) and lower (inferior) portions-not left and right.

Urinary – Includes kidney & bladder; removes wastes: The urinary system includes the kidneys and bladder, which remove nitrogenous waste and regulate water and electrolyte balance.

Endocrine – Includes the hormone-producing glands: The endocrine system includes pituitary, thyroid, adrenal glands, etc., involved in metabolism, growth, and reproduction.

Respiratory – Includes lungs, involved in gas exchange & pH balance: The lungs are central to the exchange of O₂ and CO₂, which also helps regulate blood pH.

Brain: The brain is the control center, not the effector.

Shivering: Shivering is a response, not an anatomical structure. The effector must be a structure that performs an action.

Thermoreceptors: These are the sensory receptors (detectors), not effectors.

1,3,3,1,2,4: This order is illogical-it repeats pleura in an inconsistent pattern and places visceral pleura first.

3,1,1,3,4,2: It ends with visceral pericardium followed by parietal, which is anatomically reversed.

1,3,3,1,4,2: Starts with visceral instead of parietal and ends in the wrong order.
